MAGNlFYlNG-GLASS SUPPORT FOR RETOUCHlNG-FRAMES.

SPECIFICATION forming part of Letters Patent No. 245,927, dated August23, 1881.

(No model.)

To all whom it may concern:

Be it known that I, Mrs. EMMA ALLEN, of the city of Freeport, in thecounty of Stephenson and State of Illinois, have invented a new anduseful Improvement in Magnifying-Glass Supports for ItetouchingFrames,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a perspective view of a retouchersframe with my improved apparatus attached. Fig. 2 is an enlargedperspective view of my improved apparatus, showing the same separately.

Like letters refer to like parts in the respective figures.

The object of my invention is to so mount a magnii'yingglass upon aphotographers retouching-frame that the same may be held in any desiredposition and adjusted from time to time to suit the focus of the glassand the convenience of the operator.

In Fig. 1, A represents the main portion or base of theretouching-frame, B B that part upon which the negative is placed, and Oa movable shade adjusted by means of the slotted gage b and thethumb-screw 0.

The part B B is attached to A by means of the hinges d d, and may beadjusted to any desired anglefrom a horizontal plane by means of thebraces to a.

Within the frameB B is a glass, upon which is placed the negative to beretouched. A mirror, E, pivoted within the frame A, is made to reflectthe rays of light upward through the negative D in the usual manner.

In order to do fine work in the retouching of negatives it is necessaryto use a magnifying-glass, which it is very difficult to hold in thehand and maintain the proper focus. Moreover, without this additionalburden the left hand and arm may be used to steady and support the body,and thus permit greater delicacy and accuracy of touch on the part ofthe operator.

My improved device enables this object to be accomplished.

F represents an arm, made preferably of brass or other suitable metal,with a longitudinal slot, G, formed to slide upon a bolt or screw fixedpreferably upon the left side of the frame B, and adjusted thereto bymeans of a thumb-screw, 0. At a convenient distance from the slot thearm Fis bentupward atright angles, and the holder or support H, in whichthe handle of the magnifying-glass is inserted, is attached thereto bymeans of a joint,f, so that the holder H may be moved up or down toadjust the focus of the glass, and when the proper position is reachedthe same may be maintained by means of a set-screw, g, at the jointf.

The support or holder H consists of a piece of metal tubing adjusted atright angles to the upper extension of the arm F, and so cut or notchedlongitudinally that the ends may be bent toward its center, formingsprings h h h h, which, when the handle of the magnifyingglass isinserted within the tube, press upon and hold the same in position, asshown in Fig. 1, 6 representing the handle of the glass K.

It will be seen that by loosening the thumbscrew 6 the arm F may bemoved to the right or left, or in any direction required to bring theglass over that portion of the negative to be retouched, and tighteningthe thumb-screw maintains the same in that position, the bandle alwaysbeing in a horizontal plane. As the part B B is raised or lowered andits angle changed more or less from the plane of the horizontal the lineof vision from the eye of the operator to the negative is changed in acorresponding degree. To adapt the glass to this change the holder H maybe adjusted by loosening either or both of the thumb-screws cg andmoving a portion or the whole of the arm, as desired; or the handle ofthe glass may be turned within the holder H to adapt it to the line ofvision when the focus is already obtained and no lateral movement isrequired. Thus the operator is enabled to work with greater ease andexercise a higher de gree of skill by the use of my improved apparatusthan in the old way.

Having thus described my invention, what magnifying glass when inserted,in combina- I claim, and desire to secure by Letters Patcut, is

The holder H, formed with the springs 11 h, to enable it to holdsecurely the handle of the setscrew e,for clumping and holding the arm'itself, the whole adapted to be used in con- IO nection withaphotographic retouchingframe,

in the manner and for the purpose specified.

holder is jointed, the set-screw g, for securing GEO. WOLF, the holderwhen adjusted on the arm, and the JAMES WILSON.
